If your child has eczema, it can feel like the skin is “fine” one day and flaring up the next. The tricky part is that eczema often isn’t caused by one single thing. It’s can be a combination of dryness, irritation, and everyday triggers that build up over time. Every child is different, but these are some common triggers parents should look out for:
1) Dry weather and temperature changes
Cold weather, wind, and indoor heating can dry out the skin fast. Hot weather can also trigger eczema because sweating irritates sensitive skin.
Tip: If eczema worsens with seasons, it may be linked to dry air or heat and sweat.
2) Soaps, bubble baths, and scented products
Many soaps and bath products strip the skin’s natural oils. Fragranced lotions and perfumes can also cause irritation.
Watch for: Flare-ups after bath time, or itching that starts soon after applying a product.
3) Washing powder and fabric softeners
Strong detergents and fabric softeners can leave behind residue that triggers itching and redness.
Tip: Switching to a fragrance-free detergent can make a big difference for some children.
4) Scratchy or tight clothing
Wool and rough fabrics can rub against eczema patches and make them worse. Tight clothing can also cause friction and sweating.
Better choice: Soft cotton clothing that lets the skin breathe.
5) Allergies and sensitivities
Some children flare up from environmental triggers like dust, pollen, pet hair and mould. They may also react to certain foods, but this isn’t always the cause, so it’s best not to cut foods out without medical guidance.
6) Stress, tiredness, and illness
When children are sick, overtired, or stressed, eczema can flare up more easily. This is very common and doesn’t mean you’re doing anything wrong.
How to identify your child’s triggers
You don’t need to overcomplicate it, just look for patterns.
Try noticing:
- When flare-ups happen (after bathing, after school, at night, after playing outside)
- What your child wore that day
- Whether the weather was hot, cold, or dry
- Any new products used (soap, lotion, detergent)
Eczema triggers are often small, everyday things, but once you spot them, you can reduce flare-ups and help your child feel more comfortable.
